Abstract (en)
A method for the production of biomethane (10) from biogas (100), wherein the biogas (100) is subjected to at least two steps of biogas upgrading, with intermediate removal of H<sub>2</sub>O, the biogas upgrading step consisting in the direct methanation reaction of the CO<sub>2</sub> that is present in the biogas: CO<sub>2</sub> + 4H<sub>2</sub> ↔ CH<sub>4</sub> + 2H<sub>2</sub>O.
